所以我试图为Spotify数据集创建这个决策树，并尝试了多种方法来安装这些库。

我经常犯这个错误，有人能帮我吗？

我正在使用这个python教程

如果有人有更多的机器学习资源，请发送给我！

Answer 1

我认为这是一个简单的打字错误。Scipy.misc没有名为inread的函数。该函数称为imread。用scipy.misc.imread(path)替换scipy.misc.inread(path)

Answer 2

在show_tree函数中

---

替换

img=scipy.mic.inread(路径(

---

使用

img=scipy.mic.imread(路径(

---

正确拼写：scipy.msic.imread
